AARON VREELAND, OF CEDAR GROVE, NEW JERSEY.

GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 326,358, dated September 15, 1885.

Application filed January 8, 1885. (No model.)

To all whom it may concern,.-

Be it known that I, AARON VREELAND, a citizen of the United States, residing in Cedar Grove, Essex county, New Jersey, have invented certain new and useful Improvements in Gas-Burners, fully described and represented in the following specification and the accompanying drawings, forming a part ofthe same.

This invention relates to novel means of improving the draft Within a gas-burner chimney, and is intended to alter the shape of the flame from a bat-wing, fan-tail, or

other burner which produces a flat flame, in such manner as to use the same within a vertical chimney, like a circular Argand burner, and thereby increases the degree of illumina` tion secured by the combustion of a certain amount of .gas in such a burner; and it consists in the combination, with a gas-burner adapted to form a flat flame, of a vertical chimney, a base partly closing the bottom of the same, pillars extending from the base within the chimney and above the burner and diaphragm movably supported upon the pillars, and provided with aperture for the passage of the flame.

In the drawings annexed, Figure lis a vertical section of the chimney, burner, and diaphragm. Fig. 2 is a plan of the chimney and the support for the same. Fig. 3 is a plan of' the diaphragm. Fig. 4 is a plan of a brace, I, which may be applied to the pillarse to stiften them, if required, the brace being shown only in dotted lines in Fig. l; and Fig. 5 shows a modified form of chimney-support.

A is a burner represented as attached to a pipe, B. O is a support' or base iixed at the bottom of the burner to carry the chimney D, and provided with upright pillars e,

y to carry the diaphragmf Within the chimney above the burner.

Four of the pillars are shown; and the diaphragm is represented as formed of thin sheet metal, with an oblong aperture, J, in the center for the passage of the contracted flame, and perforated with four holes to slip over the pillars, and'having bent tongues g, formed by punching, at the sides of said holes in the diaphragm, to bear elastically against the side of each pillar, and thus hold the dia phragm in its adjusted position.

In Fig. 1 the diaphragm is shown adjusted about onehalf` of' an inch above the burner, and its effect is ldisplayed in the contracted and parallel form of the flame vZ above the diaphragm. The pillars extend sufficiently above thetop of the burner to permit the sliding of the diaphragm up and down Within the necessary limits to secure the best draft upon the flame, and consequently the best combustion and illumination.

rIhe diaphragm is adjusted by removing the chimney and sliding the diaphragm upon the pillars e to the desired position, and may thus be adjusted to suit the pressure of the gas and the degree of light required.

The base O is shown in Fig. 2 as perforated with small holes h, to produce a restricted current of air to the interior of the chimney, as in Argand burners; and a rotating and partially-perforated diskI may be attached to the lower side of the base, if desired, and operated to cut off the supply of air through certain of the holes h When a very small amount of gasV is to be consumed; but a plain cross-bar-such as shown in Fig. 5-may be used as abase, if preferred. Four pins, k, are shown projected upward from the base to hold the chimney concentric with the burner; but a flanged shoulder .and vertical springs may be formed upon the base, as in Argand burners; or any other means to hold the chimney may be employed, as the same is immaterial to my invention. Thev brace I is devised merely to stiften the pillars, if it be desired to make them very slender, as it is requisite that they should hold the diaphragm centrally within the chimney, which it is not intended to touch, although fitted nearly to its interior diameter to prevent any passage of the air-draft or flame at such point.

My invention thus affords a very cheap substitute for the circular Argand burner generally used With a vertical chimney.

Having thus fully set forth the nature and object of' my invention, what I claim herein isv l. The combination, with a gas-burner adapted to form a flat flame, of a vertical chimney, a base partly closing the bottom of the same, pillars extending from the base Within the chimney and above the burner,

and a diaphragm movably supported upon IOO the pillars and provided with the aperture J for the passage of the iame, as and for the purpose set forth.

2. The combination, with a gas-burner adapted to form a flat ame, of a vertical chimney, a base partly closing the bottom of the same, pillars extending from the base Within the chimney and above the burner, and diaphragm constructed with holes7 and ro bent tongues g to press the pillars elastically,

and provided with the aperture J for the passage of the flame, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing 15 Witnesses.
